[opencms-dev] Check if element exists

[Mario Jäger]

Hi Yves,

I assume, that you are wondering over the (second) return value "true", 
because the element does not exist in your xml content. With the three 
function calls you use, methods in 
org.opencms.jsp.util.CmsJspContentAccessValueWrapper.java are used. The 
second call uses the method getIsEmpty() in that class. And that method 
also returns true for non existing values. The description for that 
method says: Returns true in case the value is empty, that is either 
null or an empty String.

Kind Regards,
Mario.
